Further to my earlier posts about drive belt noise, I think I have the solution. If your rear drive sprocket looks like the bottom one rather than the top one, change it. Belt alignment and tension is critical but if the rear sprocket is worn you get to the point where adjustments don't work. My car has done 4000 miles and the teeth look like they have worn away, the belt is still like new. I have now adjusted the belt tension to (a tight) 10mm deflection, as per the Morgan handbook. With the new sprocket there is no noise. Any guesses how long will this one last?
